Hi @salilsingh-9961 ,
The transaction replication technology is set at the SQL Server instance level (The component Publisher, Distributor, and Subscribers all acted by the database instances). Only backup/restore publication database (the database used when creating the publication) cannot migrate transactional replication related settings.
If you need to migrate the publication database involved in transactional replication to another instance of SQL Server, then you need to reconfigure transactional replication on the new instance.
